We have already proposed a resolution redistribution optical system, which alters the ratio of the horizontal anti vertical resolutions of an SLM. Using this technique increases the horizontal resolution by K times and decreases the vertical resolution by 1/K times so the horizontal viewing angle becomes approximately K times larger when our technique is used for displaying holograms. However, a conjugate image appeared. In our work, the resolution redistribution technique was improved and, thus this image is eliminated. Thus, our technique can be used to generate only an object wave. The horizontal resolution becomes K times larger and the vertical resolution becomes 1/2K times smaller. We demonstrated a fourfold enlargement of the horizontal resolution, which increased the horizontal viewing angle to 15° without generating any conjugate image.
